Oral presentation

IR Specular Reflectance (IR-SR) spectroscopy is an external reflectance technique widely used in the investigation of various materials. The IR light is specularly reflected, as described by the Fresnel equations, and contains information about the optical, dielectric, and vibrational properties of the material, which can be extracted using dispersion or Kramers–Kronig analysis. Particularly...

118. TWO-DIMENSIONAL CORRELATION ANALYSIS OF FANO RESONANCE LINE SHAPES: DISCOVERING NEW SPECTROSCOPIC FINGERPRINTS

Physical, structural chemistry, spectroscopy and electrochemistry

Oral presentation

Fano-type resonance phenomena originate from quantum interference between excitations involving discrete and continuum states, giving rise to characteristic asymmetric spectral response profiles, which are highly sensitive to changes in resonance energy, linewidth, discrete-continuum coupling strength, and the surrounding environment. Such line shapes are ubiquitous in atomic, molecular and...

45. Why the Peak Is Not Enough: Univariate Calibration Beyond the Beer–Lambert Approximation

Thomas Mayerhöfer (Leibniz Institute of Photonic Technology)

Analytical and environmental chemistry

Oral presentation

In spectrophotometric analysis, univariate calibration is often based on the intuitive assumption that the maximum of an absorption band provides the best analytical signal. This practice is closely connected to the Beer–Lambert relation, which suggests a linear dependence of absorbance on concentration and makes the most intense spectral position appear especially attractive because of its...

95. Investigation of Electroactive Geobacter sulfurreducens: Insights from Square-Wave Voltammetry and Cyclic Voltammetry

Franz Glaubitz (University of Greifswald)

Physical, structural chemistry, spectroscopy and electrochemistry

Oral presentation

Understanding electroactive biofilms is essential to advance the development of microbial fuel cells (MFCs), biological wastewater treatment, and to comprehend the bacterial communication pathways. Although decades of research have investigated electroactive bacteria (EAB), particularly G. sulfurreducens and S. oneidensis, the exact electron transfer mechanisms between EAB and electrodes...

132. Surface interaction of Ni based electrocatalyst with hydrogen peroxide

Nabi Ullah (University of Lodz)

Physical, structural chemistry, spectroscopy and electrochemistry

Oral presentation

In this study, non-stoichiometric Ni–O thin films were synthesized by magnetron sputtering, enabling precise control over their morphology independently of the chemical composition. X-ray diffraction indicated the presence of crystalline Ni(111) planes, while Raman confirmed amorphous nickel oxide. Samples with the various amount of crystalline Ni were grown. X-ray photoelectron spectroscopy...

54. An Analysis of Systems Thinking Skills in Chemistry Education Using a Bibliometric Approach

Mr Ali OZLUSOY (Dokuz Eylül University)

Education

Oral presentation

Chemistry education has historically developed through a reductionist approach focused on molecular structures, formulas, and reaction mechanisms. Although this approach has made significant contributions to the production of scientific knowledge and technological advancement, it is not sufficient on its own to address complex problems such as climate change, pollution, resource depletion, and...

125. The Effect of Chemistry-based STEM Activities on High School Students’ Argumentation Quality

Education

Oral presentation

The purpose of this study is to investigate the effect of chemistry-based STEM activities on students’ argumentation quality. The study involved 22 tenth graders in 2023–2024. Over 10 weeks, three STEM activities were implemented, each incorporating relevant learning outcomes from the chemistry topics of “Mixtures,” “Acids, Bases and Salts,” and “Chemistry Everywhere.” Students followed Hynes...
